Title: Improvements relating to electrical pressure-welding machines
IPC: B23K11/00
Filed: 1955-01-17
Abstract: 806,435. Welding by pressure. SLEE, K. V. Jan. 17, 1956 [Jan. 17, 1955], No. 1425/55. Class 83 (4). In an electric pressure welding machine having a fixed electrode and a movable electrode, the latter is mounted on a fixed support independently of the electrode actuating mechanism by a plurality of leaf spring elements arranged in the form of a trapezium or trapezoidal structure such that the movable electrode tip is constrained to move in a curved path following the coating face of the fixed electrode when the latter is deflected by welding pressure. In an embodiment a fixed electrode 5 is mounted in a holder 4 on a support 3 insulated from and secured to, possibly adjustably, the frame 2 of the machine. The upper movable electrode 11 in a holder 10 on a head 9 is mounted by leaf springs 12 secured to the head and to a part 2<SP>1</SP> of the frame. When the springs are relaxed the electrodes just touch. A spring beam 25 pivoted to the frame 2 at 14 engages with lost motion a slot 25<SP>2</SP> in the head 9 and, in the normal position when the electrodes are open, engages a bridge 26 on a box-shaped lever 13 also pivoted at 14 and having an arm 13<SP>1</SP> coupled through linkage and a member 31 to an operator's pedal. In the normal position an adjustable spring 18 acts on the lever 13, the beam 25 engages the top of the slot in the head and the part of the beam engaging the bridge 26 is acted on by a spring 27 adjustable by a screw 30. The movement of the lever arm 13<SP>1</SP> is limited by adjustable stops 22, 23. In operation, work is placed on electrode 5 and the pedal depressed to rotate the lever 13. The beam 25 maintains contact with the bridge 26 by virtue of the spring 27 and the spring 12 tending to lower the electrode 11. When the electrode 11 contacts the work the beam 25 moves through the clearance in the slot 25<SP>2</SP> to engage the bottom of the slot as in Fig. 2. The pressure of the spring 27 is applied to the work as the bridge moves away from the beam and the end of the beam remote from the head 9 moves away from a switch member 24 to operate the switch to allow welding current supplied to the electrode 5 and the frame 2 by connections 7, 8 to flow. The supply of a protective gas about the weld may be controlled by a valve opened by the arm 13<SP>1</SP> just before the electrodes touch. In modifications, the springs 12 may be parallel or non-parallel (see Fig. 4) and arranged between non-parallel supports or instead of leaf springs 12 two or more non-flexible elements may be connected to each support by short leaf springs. The electrode 11 may be mounted on the holder 9 by U-shaped springs. According to the Provisional Specification a machine of slightly modified construction, but operating in the manner above described, may be employed. Specification 806,436 is referred to.

Abstract: 106,446. Graham, E. A. Jan. 29, 1917. Push-button switches; contacts.-In a push-button switch for electric bell and other circuits, in order to keep the surfaces of the contacts clean and free from oxide, the movable contact, upon being brought into engagement with the two fixed contacts, is caused to turn thereon. The movable contact comprises a plate i upon a stem j which is mounted by means of a hole j<1> upon a pin v in engagement with inclined slots k<1>, k<2> in a stem k at the lower end of the plunger p. The plate is pressed downwards by a spring m disposed about a sleeve l which serves to keep the pin v in place. The hole j<1> is flared at each end so that the contact i can adjust itself upon the pin to take an effective bearing on the contacts h, h<1> if these contacts be irregularly disposed. A spring t serves to keep the plunger in its raised position, and a packing-ring u is provided to keep the casing a practically air-tight. A handle w is provided with two wings w<1>, w<2> so that the push can be held bv two fingers as the thumb is pressed on to the plunger p. The spring t introduces sufficient fiction to prevent the plun. ger from turning or positive means may be adopted for this purpose, and when the plunger has been depressed to bring the contact i into engagement with the fixed contacts, further depression of the plunger causes the pin v to move in the inclined slots, thus turning the contact i.

Patent GB-605995-A (GB)
Title: Improvements in or relating to the manufacture of soap
IPC: C11D13/04
Filed: 1946-01-21
Abstract: <PICT:0605995/III/1> Soaps are manufactured by continuously emulsifying glyceride fats and oils and an aqueous saponifying agent and maintaining a substantially quiescent flow of the resulting emulsion so as to allow self-saponification of the fatty matter to take place.  The expression "quiescent flow" refers to a flow of such a steady and tranquil nature as not materially to disturb or interfere with the natural sequence of the process of self-saponification. Saponification may be practically complete at this stage, or the mixture after self-saponification may be agitated, e.g. by the injection of live steam and continuous flow against a series of baffie plates, in order to complete the saponification. The fat and caustic alkali may be emulsified by injecting a jet of steam into a continuous stream of fat and caustic liquor and an emulsifying agent such as soap may be added to either the fat or the caustic liquor prior to emulsification.  Alternatively, the soap may be formed in situ by the saponification of free fatty acid, originally present in or previously added to the fat.  The aqueous saponifying agent may contain a small proportion of salt in order to lower the viscosity of the soap and diminish its swelling during the self-saponification stage.  As shown, fat, caustic liquor and steam are continuously fed by means of pipes 3, 4 and 5 respectively to the steam injector type of emulsifier 1, the caustic/fat ratio being sufficient for saponification and the rate of flow of steam adjusted to raise the emulsion to the required temperature.  The emulsion fills compartment 2A of the vessel 2 and flows over the weir plate 6 into the compartment 2B, where, after passing under baffle plate 7 it is agitated and heated by open steam from the coil 10.  Finally, the soap flows over weir plate 8 and is withdrawn down the pipe 9. Self-saponification occurs in compartment 2A, where the flow of emulsion is quiescent, and saponification is completed in compartment 2B.  Any small quantities of caustic liquor, brine or water that it may be desirable to add before the final saponification stage are sprayed from the perforated pipes 13, 14 and 15 respectively into the narrow trough 11 fitted to the cover of vessel 2 and flow over the spreader plate 12 into the stream of soap.  Specifications 201,968, 237,325 and 266,291, [all in Class 91], are referred to.
